RESUMO
Objective To explore the effect of?-3 fish oil fat emulsion on the release of pro-inflam- matory cytokines in patients with systemic inflammatory response syndrome(SIRS).Methods Forty patients with SIRS in the intensive care unit(ICU)from June 2006 to June 2007 were randomly divided into routine total parenteral nutrition(TPN)group(group A,20 cases)and?-3 fish oil fat emulsion+TPN treatment group(group B,20 cases).All the patients received treatment of parenteral nutrition with equal nitrogen content and calories.The caloric value given was 83.68 kJ?kg~(-1)?d~(-1),with 0.2 g?kg~(-1)?d~(-1)of nitrogen. Group A patients received routine TPN,and group B patients received TPN with?-3 fish oil fat emulsion 1-2 ml?kg~(-1)?d~(-1),and both regimes lasted for 7 days.The levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1)and IL-6 were checked before the treatment,and on the 1st,3rd and 7th day after the beginning of the treatment.The duration in ICU,the incidence of multiple organ dysfunction syndrome(MODS)and the mortality rates in 28 days of the two groups were also assessed.Results Compared with the routine treatment group,the levels of serum TNF-?,IL-1,and IL-6 in the?-3 fish oil fat emulsion+TPN treatment group were lower markedly(P0.05).Conclusion The emulsion of?-3 fish oil fat seems to have a protective effect on patients with SIRS through decreasing the levels of serum TNF-?,IL-1 and IL-6,thus reducing the incidence of MODS,shortening the ICU stay, and increasing the survival rate of serious patients.
